Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) This invention is applicable to variable voltage variable frequency inverters (hereinafter referred to as VVVF) and static inverters (hereinafter referred to as SIV) mounted on, for example, railway vehicles. This system relates to an on-board inspection system that inspects and tests train control components such as brake equipment.

(Conventional technology) In recent years, improvements have been made to railway vehicles to improve riding comfort and train safety as part of improvements in high-speed transportation and passenger services.
Demands such as maintenance-free equipment onboard trains are becoming increasingly diverse and increasing. For this purpose, VVVF, S
Components such as IV and brake equipment are now installed.

These devices have complicated configurations, and their tests and inspections are also complicated.

For example, when inspecting and testing a variable voltage variable frequency inverter (VVVF) for operating an induction motor, which is used to drive a train, a control voltage equivalent to the actual control voltage is externally applied, and brake pressure, variable load, etc. This is done by isometrically supplying analog signals and digital signals such as brake commands from the outside. The normal operation of the VVVF is checked using an operation indicator light.

In addition, static inverters (SIVs) are used as auxiliary power sources for trains, as power supplies for air conditioning equipment, lighting, and service equipment.
Similar to F, analog and digital signals equivalent to actual control are applied externally. Operation is also confirmed using the output voltage display and operation indicator light.

Furthermore, the brake system uses air pressure to apply the brakes in order to stop the train at the station and slow down the train.Inspection and testing of this brake system involves applying brake pressure while operating the brake valves, just as in actual control. It is being measured.

Conventionally, the arrangement of such vehicle control components on a train is generally as shown in FIG. 3. In FIG. 3, a train formation in which the necessary number of electric cars M, electric cars M', and accompanying cars T are connected between a leading car TC, which is a control car, and a tail car TC, which is another control car. The VVVFl is installed in both the M car and the M-car to control the induction motor for driving the train. The 5IV2 is also installed in both the M' car and the T car, and uses the DC voltage from the overhead wire (not shown) to generate AC voltage for the lighting, air conditioning equipment, and service equipment in the car and supplies it to them. The brake device 3 is installed in each vehicle, and controls the air pressure of each vehicle's bogie based on commands from the driver's cab.

The operation concentration display panel 4 is for centrally displaying operation indicator lights on the driver's cab for checking the operation of each of the above-mentioned devices, and is routed by an operation indicator cable 5. The operating status of each device can be checked by looking at the display on the display panel 4.

In such conventional train systems, the function, operation, installation position, shape, etc. of each system component control device are unique to each device, and inspection and testing of each device requires a dedicated tester or Measuring instruments are connected so that specialized tests, inspections, and operators of each device can perform them individually.

(Problem to be Solved by the Invention) However, in the conventional inspection test procedure for component equipment of a train system, each piece of equipment is removed from the train, transported to its respective department, and inspected individually there. In order to carry out this test, in train configuration conditions that are close to actual train operation conditions, installations such as checking for loose screws are performed by checking the condition and connecting a tester to the test connectors and test terminals prepared for each device. The main purpose was simple testing, and it was not possible to collect and test the characteristics of each device and failure record data under actual train formation conditions. For this reason, in conventional train systems, testers for inspecting and testing the component equipment,
There was a problem in that it required a large amount of testing space, testing time, etc.

Furthermore, the only way to monitor the operating status of each piece of equipment during train operation is to use operation indicator lights, and even in the unlikely event that a train malfunction occurs, the crew cannot obtain sufficient information to take corrective action. The reality is that it is impossible to know later the state of the equipment or the operating state at the time of the failure.

This invention was made to solve these conventional problems, and it is a train that can automatically inspect and test many types of equipment with different functions using a single device while they are mounted on the train. The purpose is to provide an on-vehicle inspection system.

a calculation control unit that executes an on-board inspection program for each on-board inspection device; and a test result that outputs test results of control components of each vehicle to the on-board inspection display based on the calculation results of the calculation control unit.

This information is automatically sent to the on-board inspection equipment of the leading car and the tail car via a transmission line, and displayed on the on-board inspection display to notify the driver and inspector.

In addition, by connecting the controller to the transmission line, it is possible to automatically determine the operating status and failure status of each component by sending test signals to various components and evaluating the response signals. can.
